Just be careful how you configure those networked printers. I have done some work on this in the past and found that most makes are highly vulnerable to attack and many, once pwned, can be used to pivot on to other devices on the network. This article talks about Brother printers but in reality they aren't the worst....

From what I found, printers were especially vulnerable due to the functionality they offer to the user, moreso when they were connected to AD.

I have no problem with enabling such features on cookers and cameras so long as they are done correctly. i.e. changing password defaults, firewalling it off to restrict to the internal network or NATing and defining the whitelist whom/whatever requires access, keepnig firmware up to date, etc, etc, etc......

But yes if they are asking if they should do it then I suspect they dont know what they are doing and should put whatever tech they own in a box and send it back to the manufacturer.

Things which no average punter will even consider, hence the issue.

If it's not secured by taking it out of its box and plugging it in, we're doomed.
